The present invention discloses a method for precisely measuring the weight of mass material and a nucleonic weigher employing this method. It is characterized in that the coefficient K in the nucleonic weigher's weighing formula F=KLn(Ui/U0) is dynamically modified, based on the variations of the parameters including the flowrate, the position on the conveying device, and the piled shape of the weighed mass material and the scattering of gamma radiation, thus improving the measuring precision. The nucleonic weigher manufactured with a completely enclosed framework has the merits of high measuring precision, wide application, good stability, reliable safety, small maintenance, and low cost.
